I Application iiled October 6, 1927.. Serial 1T0. 234,320.

My invention relates to ventilators of the type adapted to be installedin windows and other openings and has for its principal object toprovide a ventilator of this type which is adjustable as to length sothat it may be adapted to openings of various sizes.

Another object of the invention is to provide a ventilator which willnot obstruct the light entering the room and which may also.

exclude a large amount of dust and dirt.

These and various other objects and advantages will be apparent'from thefollowing description, to be read in conjunction with the accompanyingdrawings in which.

Figure 1 is a perspective view of a ventilator embodying my invention,as same would appearwhen mounted on-a window;

Figure 2 is a perspective view of one ofthe ventilatorfsections shown inFi re 1 but a viewing same from the opposite si e; certain parts beingbroken away.

Figure 3 is an elevation of the ventilator shown in Figure 1 but viewingsame from the opposite side.

Figure- 4 is a transverse sectional view,

taken on line 4.4 on Figure 3.

Fi re 5 a similar view taken on line 5-5 v on F1gure-3, and

Figure 6 a fragmentar sectional plan view taken on line 6-6 on igure 4.

' The embodiment shown in t e drawings is provided with a pair of rigidend pieces 11 and 11 which are opposite .hand to one another andprovided with upwardly extending ears 12 havin apertures 13 by means ofwhich the ventilator may be swingably mounted in a window casing, as-byscrews 14 preferably with the edge 15 of each en piece in closeproximity to the side rails of 0 the bottom sash and the curvature ofthe tops of ears 12 should be such'that the ventilatpr may beswung onscrews14, if so desire The body parts of the end pieces aresubstantially triangular and agulde 16 hasvone end secured to the endpiece 11 at the apex of the; triangle and overlaps a guide 16 similarlysecured to end piece 11. The'two. guides are held in sliding engagementwith I 60 one another by a pair of casings 17 which are preferably madeof thin metal and I shaped as shown in Fi 'ures 4 and 5. The outstandingportions of guides 16 and 16?- are reduced inthickness to form auxil-VENTILATOR.

iary guides 18 and 18, respectively, whose combined thicknesses.areapproximately equal to the thickness of a guide proper. Auxiliaryguide 18 overlaps auxiliary guide '18 so that, with the assistance ofcasings 17, these auxiliary guides allow the ventilator to be lengtheneA deflector plate 19 is able groove formed in end piece 11 and in agroove formed in the under side of guide 16' and is adapted tooverlapand slidingly engage a similar deflector plate 19* similarlysecured in end piece 11 and in guide 16*; auxiliary guide18 beingprovided with a groove 20 at least twice the vwidth of the groove inguide 16 so that it may accommodate both secured in a suit of thedeflector plates, as shown'in Figure 5. Deflector plates 19 may be ofany suitable materlal but have been shown as being glass plates in orderthat the ventilator will not obstructthe entrance of lightto the room.

The upper side of auxiliary guide 18*? is cut away to form a track 21and the under side of auxiliary-guide18 is cut away .to form a similartrack for accommodating a portion of one edge of a pair of screens 22and 22*. Screen 22 may be secured to end piece 11 in any suitable mannerbut has been shown as having itsend secured in a groove formed thereinby means of a wedge 23 and has a portion of its side fixed' in guide 16in a suitable groove-which forms the extension of track-21. Sgreen 22 issimilarly secured to end piece 11 and guide 16 so that, when the twoventilator sections are assembled, the free ends of screens 22 and 22are held insliding engagement with one another between auxiliary guides18 and 18 while deflector plates 19 are held in sliding engagement withone another by having one edgeof each slidably mounted in groove 20.

In order that the unconfinedcorners-of screens 22 and 22 may not sagbelow the normal plane of the screens, I'preferably providea clip 24'oneach corner in-order'to hold it in sliding contact with. 'its' companionscreen. Casings 17 have been shown-of a length to abut one another whenthe ventilator is collapsed to its shortest length but this'was done fgrillustrative purposes only and in order-to expose. auxiliary guides 18and 18 as these casings may readily be made to overlap one anotherapproximately the same distance as screens 22 and 22* and plates 18 and19 overlap one another so that the ventila or will have a finishedappearance when extended to fit any size of window 'tically no dust ordirt can enter the room through the ventilator.- Heretofore, it has beennecessary to build ventilators especially for each window but. myimproved ventilator may be made in standard sizes so that it may bequickly and easily mounted on any size window within its range and thusprovide a ventilator at a fractionlof the cost of one made es eciallyfor. a window and it is also found t at but two sizes of. theseventilators are necessary to fit practically all sizes practicalapplication thereof, it is to be understood that modifications may bemade without departing from the spirit of the invention, and hence I- donot wish to limit n self to the construction set forth, but consi erthat I am at liberty to make such changes, alterations and applicationsas fairly come within the scope of the appended claims. I

I claim I 1. A ventilator of the character described including endpieces, deflectorplates carried by the end pieces, and means secured tothe end pieces and one edge of the deflector plates for holdingthe'plates in sliding engagement with one another. 1 i

.12. A ventilator "including end pieces, a

guide on each end piece, a. deflector plate I secured to each end pieceand guide, and

means holding the guides in sliding engagement with one another.

3. A ventilator including end pieces, a guide on each end-piece, adeflector plate secured to each end piece and guide, a screen secured toeach end piece and guide, and means'holding the guides in slidingengagement with one. another. a

overlapping one another, a pair of deflectorplates secured in the endpieces and guides and slidable in one 'ofthe auxiliary guides, screenssecured in the end pieces and guides and slidable between the auxiliaryguides, and means holding the auxiliary guides in sliding engagementwith one another.

6* A ventilator includinga pair of end pieces, ears on the end piecesfor swingably mounting the ventilator on the sides of an opening, aguide'secured to each. end piece,

auxiliary guides formed on the guides and overlapping one another, aair, of deflector plates secured in the end pleces and'guides andslidable in one of the auxiliary guides,

pieces, grooved guides secured to the end pieces and overlapping eachother, a deflector plate secured to each end piece and guide andslidable in the groove in the other guide, and a casing secured to eachguide and partiallyrencircling a; art of the overlapped portions of bothgui es.

In testimony whereof I have signed my name to this specification.
